A Boeing 777 airplane lies burned on the runway after it crash landed at San Francisco International Airport July 6, 2013 in San Francisco.

Investigators are trying to determine why a Boeing 777 crash landed at SFO airport on Saturday, killing two passengers and
injuring more than 180 others. Witnesses said the Asiana Airlines flight came in low, and that its tail appeared to hit the
runway. The blackened airplane was engulfed in flames and much of its roof had been torn off. This is the first fatal
accident involving a Boeing 777; the airlines said it did not appear to be a mechanical problem, but also declined to blame
the pilot or the San Francisco control tower. We discuss the crash and what it means for commercial airline safety.

NTSB Findings on SF Plane Crash at a Glance

SAN FRANCISCO (AP) Asiana Flight 214 makes its final approach after a 10-hour flight that started in Shanghai and stopped in Seoul. A preliminary review of the crash by federal investigators turns up the following:

APPROACH PROCEEDS NORMALLY ... the plane receives clearance from air traffic control to land without its instrument landing system. Visibility is about 10 miles with winds out of the southwest at 7 knots. There are no distress calls or requests for support in the air traffic control tapes that captured the discussion between a controller and the Asiana crew.

SEVEN SECONDS OUT ... the crew asks to increase its air speed. National Traffic Safety Board chairwoman Deborah Hersman says the plane came in well below the approach speed of 137 knots that crew members had discussed.

FOUR SECONDS OUT ... the stick shaker, a yolk the pilots hold, begins shaking, indicating the plane could stall.

1.5 SECONDS OUT ... the crew calls to abort the landing and go around for another try.

CRASH ... the plane hits a seawall. The controller declares an emergency. The pilots talk to air traffic control and emergency vehicles are deployed.
